In this guide, you will find step-by-step instructions on how to charge the Audi car battery.
What you will need
A trickle charger outputs between 2 and 12 amps which is ideal for charging car batteries without damaging them.
- Park your Audi and set the parking brake. Remove the key from the ignition or if you have proximity key, keep it away from the car.
- Open the hood of your Audi by pulling the hood release under the dashboard. Once you hear the hood pop open you can stop pulling on the cable. Move to the front of the vehicle, release the hood and lift it up.
- If your Audi has a POSITIVE jump starting terminal used to jump-start the car, use it to charge the battery as well. In newer Audi vehicles it may be required to charge the battery from this post. Check your owner's manual and verify.
- In your, Audi doesn't have a jump start terminal locate the battery at the back of the engine, near the firewall. Some Audi cars have a plastic cover on top of the battery. Remove the screws that hold the cover in place, pull out the cover to access the battery.
- Connect the red clamp (+) on the positive terminal.
- Connect the black clamp (-) on the negative terminal.
- Allow the battery to charge for a few hours. Monitor the vehicle for the first couple of hours and do not leave the vehicle unattended. If the battery overheats during charging disconnect the charger immediately. We recommend using a Smart Charger to prevent the battery from overheating. If your Audi battery is completely dead it can take more than five hours to charge the battery.
If you had to jump start your Audi and are now experiencing electrical problems follow our guide on How to Read Audi Fault Codes.
If your Audi battery died because you forgot the lights or the radio on, it doesn't mean that you need to replace the battery. To fix this problem, charge the battery using a trickle charger. A trickle charger provides a small current that brings the battery back to a fully charged state.
Instructions in this guide, apply to most Audi models including A1 A3 A4 A5 A6 A7 Q3 Q5 Q7 TT.
Why you shouldn't jump-start an Audi
Of course, you can always jump start your Audi but we wouldn't recommend it unless absolutely necessary.
When you jump start an Audi with a jump box or another car, but doing so can have an impact on the life of the battery. It can also trigger low voltage fault codes in various modules and even send your Audi in the limp mode in some cases. If time is not a restraint, charge Audi battery following the directions listed above.
